ST. PAUL, Minn. – New research suggests brain tumor patients who take the seizure drug valproic acid on top of standard treatment may live longer than people who take other kinds of epilepsy medications to control seizures. The research is published in the August 31, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology. "Despite some limitations, our results suggest that the choice of seizure medications in brain tumor patients should be carefully considered as it may give people a few more months with their loved ones," said study ...

An investigation into the mysterious inner workings of the malaria parasite has revealed that it survives and proliferates in the human bloodstream thanks in part to a single, crucial chemical that the parasite produces internally. According to scientists at the University of California, San Francisco (UCSF) and Stanford Medical School, reporting today in the journal PLoS Biology, this insight immediately provides a powerful new tool for discovering and designing drugs to treat malaria, which infects hundreds of millions of people around the world each year and claims ...

Hamilton, ON (August 31, 2011) – Scientists were surprised at how fast bacteria developed resistance to the miracle antibiotic drugs when they were developed less than a century ago. Now scientists at McMaster University have found that resistance has been around for at least 30,000 years. Research findings published today in the science journal Nature show antibiotic resistance is a natural phenomenon that predates the modern clinical antibiotic use. Principal investigators for the study are Gerry Wright, scientific director of the Michael G. DeGroote Institute for Infectious ...

In this month's edition of Physics World, David Wilkinson, visiting fellow at Nottingham Trent University and former project manager in the UK Home Office Scientific Development Branch, explains how physics is at the forefront of police weapons testing, making sure that potential devices meet the strict criteria set out by the UK government. Modern police weapons, such as CS gas and TASERs, are often referred to as "less-lethal weapons" because they are designed to effectively stop people with minimum risk to both suspects and officers, and are less brutal than traditional ...

A study involving nearly 10,000 cardiac arrest patients from 10 North American regions has shown that extending the period of initial cardiopulmonary resuscitation (CPR) by paramedics and firefighters from one to three minutes provides no benefit. The study, led by Dr. Ian Stiell of the Ottawa Hospital Research Institute (OHRI), the University of Ottawa (uOttawa) and the Resuscitation Outcomes Consortium (ROC), resolves a worldwide controversy about cardiac arrest care. It is the largest randomized cardiac arrest trial in the world, published in the New England Journal ...

Researchers have undertaken the most comprehensive investigation of genetic variance in human metabolism and discovered new insights into a range of common diseases. Their work has revealed 37 new variants that are associated with concentrations of metabolites in the blood. Many of these match variants associated with diseases such as chronic kidney disease, type 2 diabetes and blood clotting. The team conducted the largest ever study of the human genome for genetic variants associated with metabolites - the biochemical compounds representing the start or end of metabolic ...

A new study suggests that Homo erectus, a precursor to modern humans, was using advanced toolmaking methods in East Africa 1.8 million years ago, at least 300,000 years earlier than previously thought. The study, published this week in Nature, raises new questions about where these tall and slender early humans originated and how they developed sophisticated tool-making technology. Homo erectus appeared about 2 million years ago, and ranged across Asia and Africa before hitting a possible evolutionary dead-end, about 70,000 years ago. Some researchers think Homo erectus ...

A faint star in the constellation of Leo (The Lion), called SDSS J102915+172927 [1], has been found to have the lowest amount of elements heavier than helium (what astronomers call "metals") of all stars yet studied. It has a mass smaller than that of the Sun and is probably more than 13 billion years old. "A widely accepted theory predicts that stars like this, with low mass and extremely low quantities of metals, shouldn't exist because the clouds of material from which they formed could never have condensed," [2] said Elisabetta Caffau (Zentrum fur Astronomie der Universitat ...

For the first time, researchers at the University of California, Davis, have demonstrated that forest trees have the ability to tap into nitrogen found in rocks, boosting the trees' growth and their ability to pull more carbon dioxide from the atmosphere. Given that carbon dioxide is the most important climate-change gas, the nitrogen in rocks could significantly affect how rapidly the earth will warm in the future, the researchers say. They report their findings in the Sept. 1 issue of the scientific journal Nature. If trees can access more nitrogen than previously ...

STANFORD, Calif. — Memo to mature, health-minded vampires: You might want to consider limiting your treats to victims under age 30. In a study to be published Sept. 1 in Nature, Stanford University School of Medicine scientists have found substances in the blood of old mice that makes young brains act older. These substances, whose levels rise with increasing age, appear to inhibit the brain's ability to produce new nerve cells critical to memory and learning. The findings raise the question of whether it might be possible to shield the brain from aging by eliminating ...

(BOSTON) – Judith A. Linden, MD, associate professor of emergency medicine at Boston University School of Medicine (BUSM) and vice chair for education in the department of emergency medicine at Boston Medical Center (BMC), has written an review article on the treatment of adult victims of sexual assault in an acute care setting that will run in the Sept. 1 issue of the New England Journal of Medicine.

Just one second, one heartbeat. That's what is needed for a new, noninvasive functional imaging technology to record data for locating the source in the heart of a dangerous cardiac arrhythmia called ventricular tachycardia (VT). VT is an abnormal, fast beating of the heart, which, if ignored, can lead to ventricular fibrillation, which causes some 400,000 cases of sudden death yearly in the United States alone. The technique, developed by a Washington University in St. Louis scientist, is called Electrocardiographic Imaging (ECGI). It combines computerized tomography ...

The green anole lizard is an agile and active creature, and so are elements of its genome. This genomic agility and other new clues have emerged from the full sequencing of the lizard's genome and may offer insights into how the genomes of humans, mammals, and their reptilian counterparts have evolved since mammals and reptiles parted ways 320 million years ago. The researchers who completed this sequencing project reported their findings August 31 online in the journal Nature. The green anole lizard (Anolis carolinensis) – a native of the Southeastern United States – ...

A specific genetic alteration has been discovered as a defining feature of epithelioid hemangioendothelioma (EHE), a rare but devastating vascular cancer. These findings have also been used to develop a new diagnostic test for this blood vessel disease. An international research effort led by Brian Rubin, M.D., Ph.D., of Cleveland Clinic's Pathology and Laboratory Medicine Institute and Lerner Research Institute, devised an innovative approach to reveal the genetic alteration thought to cause EHE, which is considered uncommon: it comprises less than one percent of all ...

Breast cancer patients over the age of 60 with early-stage, hormone-responsive small tumors who forego adjuvant endocrine, also called hormonal therapy, are not at an increased risk of mortality compared to women of the same age without breast cancer, according to a study published Aug. 31 in the Journal of the National Cancer Institute. The use of hormonal therapy has increased in breast cancer patients overall, and the 2009 St. Gallen International Breast Cancer Conference recommended hormonal therapy for almost all patients with hormone-responsive disease. But previous ...

University of British Columbia scientists may have uncovered a new explanation for how Alzheimer's disease destroys the brain – a profusion of blood vessels. While the death of cells, whether they are in the walls of blood vessels or in brain tissue, has been a major focus of Alzheimer's disease research, a team led by Wilfred Jefferies, a professor in UBC's Michael Smith Laboratories, has shown that the neurodegenerative disease might in fact be caused by the propagation of cells in blood vessel walls. Examining brain tissue from mouse models of Alzheimer's disease, ...
